Morrison says: 'My first two choices were Robert Powell who had to be Jesus, recreating the famous role played in Franco Zeffirelli's Jesus of Nazareth and Julie Walters, who was asked to play Mary Magdalene (there has been speculation about whether it was Mary Magdalene or John the Apostle who was seated next to Jesus) and they both readily agreed. Their enthusiasm and influence helped to bring together this outstanding group of actors'.
